Oval-cycloidal Magnetic Structure with Phase-shift in the Non-centrosymmetric Tetragonal Compound CePdSi₃

Review on crystal structures and magnetic properties of RTX 3 materials

“…Later, Ueta et al [125] reported a spin density wave magnetic structure below T N 1 = 4.8 K, the transition from incommensurate to the commensurate magnetic structure below T N 2 = 2.8 K through the first order transition and a commensurate magnetic structure below T N 3 = 2.2 K. The incommensurate magnetic structure below 4.8 K is described by a propagation vector k 1 = (± 0.283, 0, 0), and the commensurate magnetic structure below 2.2 K is described by two vectors k 2 = (± 0.25, 0, 0) and k 3 = (± 0.25, 0, ± 1) [125]. Recently, CePtSi 3 revealed more than six magnetic phases in contrast to the previously reported three magnetic phases [68].…”

“…CePdSi 3 shows complex magnetic properties with three successive magnetic phase transitions below T N1 = 4.85 K, T N2 = 2.78 K, and T N3 = 2.30 K [126]. Recently, Ueta et al [68] reported a neutron diffraction study of CePdSi 3 , which revealed an incommensurate magnetic structure with a propagation vector k 1 = (0.315, 0, 0) below T N1 and an oval-cycloidal structure below T N3 . Furthermore, the study suggests multiple metamagnetic transitions due to the influence of the antisymmetric spin-orbit interaction.…”

“…EuT Ge 3 (T = Co, Ni, Rh, Pd, Ir and Pt) [42], EuT Si 3 (T = Pt, Rh and Ir) [65,66], CePtSi 3 [67] were grown using liquid Sn and In flux. Single crystals of CePdSi 3 [68], SmNiSi 3 [69] and CeT Ge 3 (T = Co, Rh, Ir) [70] were synthesized using liquid Pb, Ga and Bi flux, respectively. Similarly, single crystals of CeZnAl 3 and RCuGa 3 (R= Pr, Nd and Gd), RNiGe 3 (R = Ce-Nd, Sm, Gd-Lu) [71][72][73], CePdSb 3 [37], CeCuGa 3 [74] and CeTiGe 3 [58] were synthesized using the self-flux method.…”
